Review on Holikme 15-Foot Dryer Vent Cleaning Brush, Lint Remover, Extendable up to 15 Feet, Synthetic Brush Head, Compatible with or Without Power Drill by Jennifer Clark

Bought based on length and reviews to skip my dryer air duct which has 'never been cleaned in 18 years'. My channel starts at floor level in my basement, goes up and behind the wall, and turns right and then to the wall and out. Approximately 14 feet stands with a 90 degree turn. No box or instructions, just poles, brush and 'Turn Right Only' sticker in mailer. If you can't figure out how to use it, you probably just need to call a guy to do it for you. The hardest part about getting this through my channel was stopping every 3 or so to add more bars. I was able to add 2 at a time by using the drill at low speed and pushing/guiding the rods into the channel. I completed 190 with no problems and covered the entire length in no time. Turn on the vacuum in the shop while you return. I then asked my wife to use the leaf blower in the back room and I went outside and ran the brush the other way. OMG the amount of lint that went through was amazing! Wear a mask! Buy this and save $12 at your local store. I will use this annually or more often. Our dryer now dries twice as fast.
